Metra is adding service Saturday to accommodate passengers heading to and from the Arlington Million.
To accommodate crowds going to the race, Metra will add capacity all day to trains on its Union Pacific Northwest Line, which stops at Arlington International Racecourse.
Metra also is adding one downtown-bound train, which will depart the park at 6:15 p.m. and express to Jefferson Park before making all stops to the Ogilvie Transportation Center, arriving there at 7:01 p.m.
